Factual error: When the soldiers are asked to find out what gifts Andy is getting at his birthday party, the set out down stairs with half of a baby monitor. Well, any parent who owns one knows that there are 2 pieces to a baby monitor. One half (the larger half) is the receiving end (that takes in the noises) and a smaller half which is the transmitting part (the half that sends out the noises). The half that the soldiers take downstairs to talk through is the wrong half. They take the half that the noise comes OUT of. So, really, they should NOT be able to speak into this part - in real life, they'd hear what was happening up in Andy's room. (00:09:18)
